I find it to perform worse than the first FO3 on my PC. I think they need to optimize the code for it. So far it is fun though. I am maybe an hour and a half in.
I don't like how books/magazines only give you a temp skill boost. Like after minutes you just magically forget what you learned? I like the old way better where books were more rare but permanent skill increases.
Also, they took out some of my favorite perks. I used to always get gifted and bloody mess, both seem to be missing.
I have played and beat every fallout game that has ever existed. 1 and 2 are still the best so far as content goes. They had the best items, perks, and the most freedom. You could shoot children in the groin in the original games. Now that all video games must be rated, that is gone. Back in the good old days when gaming was like the wild west with no regulation. Now everything has this parental warning crap on it.
The game itself is fun, and I liked Fallout 3, but I don't think 3 ever really touched how awesome 1 and 2 were. Going back and playing the originals is tough though, because the technology behind them is so dated and it shows. Plus not too many games these days are turn based.
I did like Fallout Tactics though.
